§ Canthonidia rubromaculata ( Blanchard, 1846)

Canthon rubromaculatum Blanchard 1846: 165 ( Bolivia)

= Canthonidia hirsuta Paulian 1939: 25 ( French Guiana)

Distribution. French Guiana: Paulian 1939: 25 (as C. hirsuta ); Blackwelder 1944: 202 (as C. hirsuta ). “Guianas”: Vulcano and Pereira 1964: 590 (?). Other: Blanchard 1846: 165 (Bolivia - as Canthon rubromaculatum ); Gillet 1911b: 32 (Bolivia - as Canthon rubromaculatus ); Balthasar 1939e: 190 (Bolivia - as Canthon rubromaculatus ); Blackwelder 1944: 201 (Bolivia - as Canthon rubromaculatum ); Vulcano and Pereira 1964: 590 (Bolivia).

Note. According to Boilly and Vaz-de-Mello (2013: 109), the specimen from French Guiana on which Paulian (1939: 25) based his description of Canthonidia hirsuta was probably mislabeled. The records for French Guiana in Blackwelder (1944: 202) and Vulcano and Pereira (1964: 590) are likely based on Paulian’s description. Neither Canthonidia hirsuta nor C. rubromaculata , of which it is now a synonym, have been recorded again for French Guiana, and we are not aware of any records from the other Guianas. The species appears to be restricted to Bolivia and we regard it as not occurring in the research area.
